Abstract

Under one aspect, a collection of particles includes at least about 60% non-spherical particles, each of the non-spherical particles including a first spheroid having a first polymer composition; a second spheroid having a second polymer composition; and a third spheroid having a third polymer composition. The first and second polymer compositions at least partially interpenetrate, thus joining the first and second spheroids together, and the third polymer composition at least partially interpenetrates at least one of the first and second polymer compositions at a juncture of the third spheroid with at least one of the first and second spheroids.
